"The lead investigator, former assistant US attorney Reid Schar, stated that Bowman's failure to report the alleged assault had consequences, eventually leading to the perpetrator committing further acts of sexual abuse.”
Here's the thing though, what was true then, is not even true today. Nobody would ever suggest a sexual assault be investigated internally now, and that was one of the recommendations. There are some laws that make disclosure mandatory now, but there was not then, anywhere, which is why they did nothing wrong. 15 years ago the majority of experts still believed a victim could be expected to advocate for themselves, but know we know better.
I have deep experience and knowledge of policy and laws on this topic and what Bowman alluded to in the presser, that it's hard to believe someone you know could so something like this, is the endpoint of 99.9% of investigations. It shows he understands the reasons for the mistakes, which is rare.
Ultimately, they were faced with two people saying two different things. When you don't have all the information, it's very hard to ruin someone's life based on a belief. That's why disclosure needs to happen, so people with inherent biases are not tasked with making decisions.
A lawyer today, would speak entirely different, because that is how much this field has grown. Lots of people in this thread are viewing past events with knowledge of current norms and practices, that did not exist 15 years. Even the investigation post event would be considered passe, which shows how quickly things have moved. 15 years ago there was no good policy, laws, or theory to fall back on, everyone had to figure it out themselves.
